is this 7/(3x+54) or 7/(3x*54) or something like that

OpenStudy (anonymous):

ok the -18 is excluded becouse 3*(-18)+54 would be 0 and you cant't devide by 0

OpenStudy (anonymous):

i assumed it was 7/(3x+54) not (7/3x)+54 how your spelling would usually be interpreted (in that case 0 would be exluded)
